INTRODUCTION: The aim of this study was to investigate the mechanism of how micro-osteoperforations (MOPs) accelerate tooth movement. We focused on inflammation, cell proliferation, and apoptosis of periodontal ligament cells and performed immunostaining of MOPs exposed to tumor necrosis factor-alpha (TNF-α), proliferating cell nuclear antigen (PCNA), and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) during experimental tooth movement. METHODS: Eleven-week-old male Wistar rats were divided into 2 groups: (1) 10 g of orthodontic force applied to the maxillary first molar (TM) and (2) force application plus 3 small perforations of the cortical plate (TM + MOPs)...

Patients with root resorption and malocclusion can benefit from orthodontic treatment with or without surgery. However, orthodontics has a risk of inducing or aggravating root resorption, therefore the duration of the treatment is of utmost importance. In this paper, a surgery-first protocol with lower jaw advancement and precise interdental alveolar osteotomies was conducted to accelerate the treatment of a 14-year-old female patient who presented with a Class II division 2 malocclusion, anterior dental crowding and idiopathic root resorption...

In this paper, we propose a device that can induce vibration to potentially accelerate the rate of orthodontic tooth movement and thus reduce the duration of the orthodontic treatment. This is accomplished by harmonically exciting a polyvinylidene fluoride (PVDF) piezoelectric actuators to generate vibration and hence generate cyclic loading at 30 Hz. PVDF is a popular piezoelectric polymer because of its high flexibility, biocompatibility, and low cost. Generally, application of cyclic loading (vibration) reverses bone loss, stimulates bone mass, induces cranial growth, and accelerates tooth movement...

Clinical evidence has suggested that surgical corticotomy of the alveolar bone can accelerate local orthodontic tooth movement (OTM), but the underlying cell and molecular mechanisms remain largely unclear. The present study examined the role of macrophages played in corticotomy-assisted OTM. Orthodontic nickel-titanium springs were applied to the left maxillary first molars of rats or mice to induce OTM with or without corticotomy. Corticotomy enhanced OTM distance by accelerating movement through induction of local osteoclastogenesis and macrophage infiltration during OTM...

Modalities that increase the rate of tooth movement have received considerable attention, but direct comparisons between devices are rare. Here, we contrasted 2 mechanical vibratory devices designed to directly transfer vibrations into alveolar bone as a means to influence bone remodeling. To this end, 3 cells types intimately involved in modulating tooth movements-osteoblasts, periodontal ligament fibroblasts, and osteoclasts-were subjected to in vitro vibrations at bout durations prescribed by the manufacturers...

This study evaluated the effects of hyaluronic acid (HA) on bone repair of human dental sockets. Thirty-two lower first premolars were extracted from 16 patients (2 per patient) for orthodontic reasons. Following the extractions, one socket was randomly filled with 1% HA gel, while the other was allowed to naturally fill with blood clot. After 30 and 90 days of surgery, patients underwent cone beam computed tomography. Five central orthoradial slices were captured from each socket. The gray intensity was measured in each image and results were reported as mean percentage of bone formation...
